3.2.8. Check and adjustment of gaps of valves

GENERAL INFORMATION

Sequence of adjustment of gaps of valves at installation of the piston of the first cylinder in situation VMT

Е – camshaft of inlet valves

And – a camshaft of final valves

Sequence of adjustment of gaps of valves at installation of the piston of the fourth cylinder in situation VMT

Е – camshaft of inlet valves

And – a camshaft of final valves

Use of the special tool for pressing of pushers in their openings

For withdrawal adjusting shayub the screw-driver and a magnet are used.

On diesel engines gaps of valves are checked and regulated on the cold engine.

PERFORMANCE ORDER
1. Uncover heads of cylinders.
2. Turn the engine before installation of the piston of the first cylinder in situation VMT. Thus the tag on a pulley has to coincide with a pin on the case of the oil pump.
3. Check that pushers of valves of the first cylinder have a small side play, and pushers of valves of the fourth cylinder sit densely. If it not so, turn the engine on one turn.
4. Measure according to rice. Sequence of adjustment of gaps of valves at installation of the piston of the first cylinder in situation VMT by means of the probes inserted between a pusher and a surface of a cam, gaps of valves. Gaps inlet (E) and final (And) valves not on all engines are identical and are given in size tables and adjustments.
5. Turn the engine on one complete revolution and measure the gaps specified rice. Sequence of adjustment of gaps of valves at installation of the piston of the fourth cylinder in situation VMT. A sign of the correct adjustment is when the end of the probe is entered, and then under easy pressing the probe caves in and enters inside.
6. For adjustment of gaps of valves it is necessary to replace adjusting washers from the top party of pushers, but removal and installation of adjusting washers requires the special tool. For this purpose turn a cranked shaft before installation of the corresponding cam an edge up and by means of the special tool shown on rice. Use of the special tool for pressing of pushers in their openings, or otherwise press a pusher inside that it was possible to take and pull out a small screw-driver and a magnet an adjusting washer.
7. Before pressing a pusher, it should be turned so that the notch from the top party was turned to candles. Both pushers nestle at the same time, that is it is necessary to watch that both pushers nestled an adaptation leg.
8. Measure the removed washer by a micrometer and write down result.
9. Calculate thickness of a new washer for providing the demanded valve gap. Thus the following formula is used:
Inlet valves: N = T + (And – 0,25 mm);
Final valves: N = T + (And – 0,30 mm), where "T" – thickness of the removed washer. "And" – the measured gap of the valve and "N" – thickness to the new, subject installation of a washer.
10. Choose a washer which on thickness is closest to the demanded gap. There is a row from 25 sizes of washers from 2,2 mm to 3,4 mm thick through 0,05 mm.
11. For installation of an adjusting washer again press a pusher inside and insert a washer.
12. Measure a valve gap as it was described above.
13. Adjust gaps of other valves.

Prevention

The adjusting washer should not fall in the engine at all. In order to avoid it use a small screw-driver and a magnet as it is shown on rice. Use of the special tool for pressing of pushers in their openings. The washer can be after that is put forward aside and "grabbed" with a magnet.
